Known as Open Catalyst Experiments 2024 (OCx24), the research was carried out by Meta, VSParticle (VSP) and the University of Toronto. Over the course of just a few months, the project saw 525 catalyst materials identified, synthesised and tested. It’s claimed the materials could play a key role in areas such as carbon capture, hydrogen production and battery chemistry.
Meta’s Fundamental AI Research (FAIR) team has been working on speeding up the discovery of electrocatalysts, but the large and diverse datasets needed for AI to work effectively are not available. OCx24 sought to address this issue to some degree, creating an open-source database that can help bridge the data gap.
“Through this collaboration, we’re breaking new ground in material discovery,” said Larry Zitnick, research director at Meta AI.
“It marks a significant leap in our ability to predict and validate materials that are critical for clean energy solutions. The results we’re seeing with electrocatalysts demonstrate the real-world potential of AI in addressing urgent climate challenges.”

A VSP-P1 nanoprinter was used to synthesise 525 materials identified by Meta’s FAIR team as having strong potential for CO2 Reduction Reactions (CO2RR). Using a process known as spark ablation, the materials were vaporised then deposited as thin, nanoporous films. These films were shared with researchers at the University of Toronto who tested how well each one performed under a range of industrial conditions.
The findings were fed into a database from which researchers were able to validate the AI predictions against real-world results, identifying hundreds of potential low-cost catalysts for key reactions. According to the researchers, the results can now also be used to train and further refine the AI models.
“By producing unique electrocatalysts at unprecedented speed, our partnership with Meta and the University of Toronto is not only helping to validate years of theory, but it’s shortening the discovery-to-application timeline; clearing a bottleneck that has held advanced materials back for decades,” said Aaike van Vugt, co-founder and CEO of VSParticle.
